Groundhogs vs. Beavers: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Published on June 22, 2026
Groundhogs are burrowing rodents known for hibernation, while beavers are aquatic rodents famous for building dams and lodges.

Key Differences
Groundhogs, also known as woodchucks, are part of the marmot family, primarily living in burrows in open fields and edges of woodlands. Beavers, on the other hand, are known for their aquatic habitat, living in rivers, streams, and ponds, where they build dams and lodges.
A distinct feature of groundhogs is their ability to hibernate during the winter months in underground burrows. Beavers do not hibernate but remain active throughout the winter, often staying within the vicinity of their lodges and dams.
Groundhogs are smaller compared to beavers, typically weighing around 6 to 12 pounds, with a shorter tail. Beavers are one of the largest rodents in North America, weighing between 30 to 60 pounds, with a distinctive large, flat tail used for swimming and signaling danger.
The diet of a groundhog primarily consists of vegetation such as grasses, plants, fruits, and tree bark. Beavers, however, are known for their wood-eating habits, feeding mainly on the bark, twigs, and leaves of trees.
Groundhogs have a significant role in folklore, especially in the United States, where Groundhog Day predicts the arrival of spring. Beavers are often recognized for their environmental impact, particularly in water management and ecosystem engineering.
